Abstract
Several hymenopterous parasites ofScolytus multistriatus are attracted to components of its aggregation pheromone, multilure.Cheiropachus colon, Entedon leucogramma, Dendrosoter protuberans, Spathius benefactor, andCerocephala eccoptogastri are attracted in various degrees to multilure, its components (multistriatin, 4-methyl-3-heptanol, and cubebene), and component combinations.C. colon was trapped in greatest numbers, yet was usually less numerous thanE. leucogramma andD. protuberans in the study area. Impact of traps onC. colon may conceivably be reduced by multistriatin content in baits and/or by withholding traps untilS. multistriatus flight begins.
